After more than a year of ongoing rumors and more recent teasing from Valve Software, the Half-Life
studio confirmed that Portal 2
, the sequel to 2007's revered puzzle-shooter, is coming this holiday.
The original Portal
released with Valve's Orange Box
compilation, which also included Team Fortress 2
and Half-Life 2
along with its two subsequent episodes. The Orange Box
released on PlayStation 3, Xbox 360 and PC, although Valve did not confirm platforms or specific release dates for the sequel.
The critically-lauded original received over 70 awards according to Valve. Portal
came about following a project from DigiPen Institute of Technology students who created a game called Narbacular Drop
, which featured portal-style gameplay. Valve hired on a number of Narbacular
's team members to work on Portal
In recent days, Valve had been dropping hints that something new was on the way by updating the existing Portal
game with abstract clues.
